服務(wù)器
nginx做為服務(wù)器，mongo為數(shù)據(jù)庫支持，flask為python語言的web框架，利用docker的容器特性，可以簡單地部署在linux服務(wù)器上
項(xiàng)目準(zhǔn)備
項(xiàng)目主要目錄如下
__ project-name |__ docker-file |__ ningx |__ dockerfile |__ conf |__ nginx.conf |__ flask |__ dockerfile |__ requirements.txt |__ mongo |__ dockerfile |__ setup.sh |__ docker-compose.yml |__ src |__ app |__ ... |__ run.py簡要說明
docker-file目錄為docker部署的配置文件
src目錄為flask應(yīng)用的python代碼
docker的詳細(xì)配置
docker-compose配置

/mongo/dockerfile的內(nèi)容如下

該文件的目的是，啟動(dòng)mongodb后創(chuàng)建一個(gè)密碼為test的用戶test，并賦予它數(shù)據(jù)庫test的讀寫操作
#!/bin/bashmongo <<eofuse admin;db.auth(\\\'root\\\', \\\'123456\\\');use dmx_aluminum;db.createuser({user:\\\'test\\\',\\\'test\\\',roles:[{role:\\\'readwrite\\\',db:\\\'test\\\'}]});db.createcollection(user);eofflask應(yīng)用的配置
/flask/dockerfile的內(nèi)容如下

此處注釋了調(diào)試用的 app.run()，發(fā)布時(shí)用gunicorn啟動(dòng)

/nginx/dockerfile的內(nèi)容如下

進(jìn)入docker-flie目錄 cd docker-flie
啟動(dòng)docker docker-compose up
